Definitions

  • the invention relates to an adhesive tape for joining the start of a new paper roll to the end of an old, expiring paper roll.
  • the thickness of a coating depends not only on the distance between the web to be coated and the doctor blade which draws the coat smooth but also on the rate of advance. Furthermore, a part is also played by the temperature of the product to be coated and the temperature of the coating material; both can only be consistent if the web speed is constant.
  • Paper however, can be neither supplied nor delivered as a continuous product of arbitrary length; instead, it takes the form of a wound coil having a winding length which, although large, is still finite.
  • a reel of this kind shows the form of an Archimedes spiral; since, however, the thickness of the paper is very low in relation to the diameter of the reel, a paper reel of this kind gives the appearance of a roll; accordingly, these paper reels are referred to in the jargon of those skilled in the art as “paper rolls”.
  • CA 2,113,932 filed Jan. 21, 1994 and published Mar. 21, 1995, which indicates an adhesive tape having a splittable paper backing 12 and also pressure sensitive adhesive layers 14 and 16 (one on the top and one on the bottom of said backing 12 ) which in turn are each protected up until the time of their use by a liner tape 18 or 20 , respectively.
  • the bottom adhesive side of the double-sided adhesive tape is designed in this case to be adhered to the winding which is second from the top, approximately at the point where the topmost winding of the new roll ends, at the beginning of the joining operation. Subsequently, the topmost winding is to be attached over it, on the topside of the adhesive tape, in such a way that it occupies a part, a third for example, of the upper adhesive layer.
  • the new roll, held together by the lower adhesive layer is then accelerated to the correct web speed, i.e., synchronized, and then attached to the end of the old roll by that part of the upper adhesive layer which is still free.
  • an adhesive tape which has an adhesive layer essentially only on its topside.
  • the cover sheet of this adhesive layer is composed of two parts ( 4 and 5 ) separated from one another by a longitudinal seam ( 9 ).
  • a narrow adhesive strip 7 or 70
  • a cover sheet 8
  • the adhesive force of this adhesive strip toward paper is said to be substantially higher than toward the adhesive tape backing to which the adhesive strip adheres by its other side.
  • This narrow adhesive strip serves to fasten this adhesive tape and hence the topmost winding to the winding second from the top of the new paper roll, the bond strength ratio mentioned being intended to bring about the separation of this bond at the moment when the start of this new roll has joined, by virtue of the adhesive tape, to the end of the old roll, and specifically a separation such that the adhesive strip ( 7 or 70 ) remains on the roll (which is referred to therein as a drum), i.e., detaches from the bridging adhesive tape.
  • said adhesive strip ( 7 or 70 ) can also be a double-sided adhesive tape.
  • the adhesive tape backing must be made of paper.
  • the simplest way of promoting the detachment on the side facing the adhesive strip ( 7 / 70 ) is to roughen the paper backing at that very spot.
  • the first adhesive layer is intended to extend over the width of the backing part, essentially from the first longitudinal edge of the backing part to a “first position” situated toward its center, while the second adhesive layer is intended to begin at or behind said first position, without overlapping with it, and to extend over the width of the backing part to a “second position”, which is situated toward the second longitudinal edge of the backing part.
  • both adhesive layers are produced in one piece from the same adhesive.
  • FIGS. 6 show that said “first position” coincides with the point at which the liner tape is slit and so is divided into two halves 10 and 11 .
  • FIG. 11 of this document shows a more expensive to prepare but easier to handle embodiment according to which both liner tape halves 10 and 11 are situated not flush against one another but centrally above one another, like roof tiles, to make the projecting, filmlike end of the liner tape easier to grasp.
  • the reason for this is that, with the roll at standstill, the first adhesive layer can be adhered to the paper of the new roll and, furthermore, by prompt preparation of the splice, the adhesive there can be given many seconds, or indeed a time in the range of minutes, in order to attain full stability, whereas the second adhesive layer has to develop the necessary stability within the millisecond range and, furthermore, is heftily loaded by virtue of the fact that 100% synchronization is never completely achieved, so that the small difference in web speed which remains at the time of contact discharges itself in a jolt, while a small slip and the maximum shear stress occurs in the join.
  • the products of the tesa® EasySplice® family also have a mechanism for separating the roll fastening, i.e., the temporary connection between the topmost winding and the winding second from the top of the new paper roll, namely by paper splitting, as already taught in U.S. Pat. No. 2,920,835 and U.S. Pat. No. 3,006,568.
  • the adhesive layer ( 7 / 70 ) referred to by the citation addressed above is replaced here by a double-sided adhesive tape with a paper backing of the kind, approximately in its center, which splits at the moment of detachment.
  • the inventors set themselves the object of providing a further means or a further measure to ensure that the “second adhesive layer” in the terminology of DE 694 07 822 T2 stands up to the high load.
  • an adhesive tape for joining two material webs (I, II), preferably for joining the start (A) of a new paper roll (P) to the end (E) of an old, expiring paper roll,
  • This advantage can be utilized in the form of a further increase in product reliability and/or in the form of a narrowing of the adhesive tape, thereby further reducing the running uniformity disturbances which occur when the site of the splice passes through apparatus such as roll pairs, etc.
  • the two bonding areas are appropriately prepared from two different adhesives.
  • the higher resistance is preferably twice as high, with particular preference four times as high.
  • this specialization of the adhesive also makes it possible to keep the first adhesive layer of the adhesive splicing tape particularly narrow—that is, to keep it particularly short as viewed in the running direction of the paper to be joined.
  • the shortening of the bonding zones brings about a reduction in the attendant disturbance to uniformity in the running of the paper when the splice site runs through roll pairs or over deflecting rollers or other working devices.
  • the first adhesive has a shear resistance which is preferably at least 40% greater than that of the second adhesive; optimally its shear resistance is greater by a factor of at least 3.
  • the formula of the second adhesive i.e., the adhesive of the second adhesive layer ( 2 . 2 )—which is intended to attach within a very short contact time to the end of the old, expiring material web (preferably: paper web), which is running at full speed—to be formulated for a higher tack than the formula of the first adhesive.
  • the tack of this second adhesive is made greater by a factor of at least 3 than the tack of the first adhesive, preferably by a factor of between 8 and 12.
  • the shear resistance of the second adhesive is less than that of the first; at least in those cases where this is accepted, this second adhesive layer ought—in a way which in principle is known per se—to be broader than the first adhesive layer in order to compensate this disadvantage, to conform to the teaching that a chain is only as strong as its weakest link.
  • the more strongly adhesive (more tacky) adhesive layer overlies the more weakly adhesive layer, i.e., the second over the first. Accordingly, the more tacky adhesive layer comes to lie facing the counterpiece that is to be bonded (in this case paper), and the advantage of the high initial bonding is maximized. For this it is necessary to accept the more tacky adhesive layer being located further from the adhesive tape backing in the region of overlap, although this has hardly any disruptive effect especially when the first adhesive layer below it is—as recommended—particularly shear-resistant.
  • the first adhesive layer extends over the entire width of the adhesive tape.
  • an increase in compression is achieved at the beginning of the entry of the second adhesive layer into the contact zone.
  • this variant is easier to produce. Specifically, it avoids the danger of including air bubbles at the site at which otherwise the second adhesive layer would come down onto the backing: instances of detachment may occur starting from such inclusions.
  • the more tacky (second) adhesive layer should be situated at the top, in other words at a greater distance from the backing, while the more shear-resistant (first) adhesive layer lies at the bottom, in other words closer to the backing or, preferably directly on the backing.
  • the variants whose first adhesive layer is not applied over the full area have, on the one hand, the advantage of being able to manage with less adhesive, and hence of being able to be somewhat cheaper, and secondly of keeping the region of highest flexural rigidity in the splice smaller and so of improving the smooth running of the paper that is being produced or processed, as compared with the current state of the art.
  • the invention it becomes possible to give a narrower dimension to the adhesive strip for joining the two paper webs, thereby minimizing the disruptive influence of the strip in the further processing of the paper.
  • the imbalance in a roll containing a splice would be reduced.
  • the optimization of the second adhesive layer can also be utilized to allow greater slip and so to allow the jerk which is produced during joining, as result of the synchronization mismatch, to be particularly gentle, which could be the key to a further increase in the permissible paper running speed.
  • the invention is illustrated below with reference to two exemplary embodiments, the first of which is depicted two-dimensionally in FIGS. 1 to 7 and the second in FIGS. 8 to 14 ; for simplification, the third dimension has not been depicted, which can be allowed here since the sectional planes depicted is [sic] constant over the entire length of the adhesive tapes depicted and over the width of the paper webs to be joined.
  • the preferred width of an adhesive splicing tape of the invention is smaller by several orders of magnitude than the diameter of the new paper roll, which in present-day standard practice can be between 80 cm and 3 m, which is why the curvature of the corresponding paper web sections of the new roll has likewise not been depicted.
  • FIG. 1 shows an adhesive splicing tape of the invention whose first adhesive layer does not extend over the entire width of the adhesive tape;
  • FIG. 2 shows the same adhesive tape as FIG. 1 but now already adhered to the paper ply or winding second from the top of the new paper roll;
  • FIG. 3 shows the same as FIG. 2 but now with the liner tape already removed from the first adhesive layer
  • FIG. 5 shows the same as FIG. 4 but following removal of the line of tape from the second adhesive layer, after which the paper roll will now actually be accelerated;
  • FIG. 6 shows the moment at which the new paper roll, prepared as per FIG. 5 and accelerated to the correct rotational speed, is led up to the old paper web and pressed against it, after which the two paper webs are bonded;
  • FIG. 7 shows the tearing—which occurs about half a millisecond to one millisecond later—of the fasten of the new paper roll P, so that the following wound plies can now be removed as well.
  • FIG. 8 shows an adhesive splicing tape of the invention whose first adhesive layer does not extend over the entire width of the adhesive tape
  • FIG. 9 shows the same adhesive tape as FIG. 8 but now already adhered to the paper ply or winding second from the top of the new paper roll;
  • FIG. 10 shows the same as FIG. 9 but with now the liner tape already removed from the first adhesive layer
  • FIG. 12 shows the same as FIG. 11 but following removal of the line of tape from the second adhesive layer, after which the paper roll with its bonding-ready adhesive layer will now actually be accelerated;
  • FIG. 13 shows the moment at which the new paper roll, prepared as per FIG. 12 and accelerated to the correct rotational speed, is led up to the old paper web and pressed against it, after which the two paper webs are bonded;
  • FIG. 14 shows the tearing—which occurs about half a millisecond to one millisecond later—of the fasten of the new paper roll P, so that the following wound plies can now be removed as well.
  • FIG. 1 shows an adhesive splicing tape K of the invention whose first adhesive layer 2 . 1 does not extend over the entire width of the adhesive tape; instead, it extends from a first position, labeled “a”, which should be at least in the vicinity of a first boundary edge 4 . 1 and which in this exemplary embodiment is located exactly at the boundary edge 4 . 1 , to a position b, which in the figures lies further to the right and yet is still nearer to the first boundary edge 4 . 1 shown on the left than to the second boundary edge 4 . 2 shown on the right.

  • the second adhesive layer 2 . 2 of said adhesive tape K extends on the same side of the backing 1 , which in the context of this specification is also referred to as the top face; specifically, it extends from a position c, which is also called the “third position”, to a position d, which is also called the “fourth position”.
  • position c is nearer to the first boundary edge 4 . 1 than is position b.
  • c is further to the left than b.
  • the fourth position d is not only in the vicinity of the other (right) boundary edge 4 . 2 of the backing but in fact is exactly there.

  • both adhesive layers are composed of different adhesives
  • the first adhesive layer 2 . 1 here depicted on the left, ought to have a higher shear resistance than the second second [sic] adhesive layer 2 . 2 , which is on the right and has an overlap, while the latter layer ( 2 . 2 ) ought to have the higher tack.
  • both adhesive layers 2 . 1 and 2 . 2 ought each to be lined with a liner tape 3 . 1 and 3 . 2 respectively, in which case the liner tape 3 . 1 need of course only extend rightward to the extent that the adhesive layer 2 . 1 , which extends further rightward, is not already covered in any case by the adhesive layer 2 . 2 .

  • the adhesive tape K of the invention is easier to use if the liner tapes 3 . 1 and 3 . 2 project beyond the lined bonding area to some extent, at least on one side, since in that case they are easier to grasp with the fingers for the purpose of initiating a detachment. This situation is depicted in FIG. 1 , while in all subsequent figures this detail has been omitted in order, firstly, for this less expensive solution to be illustrated and, secondly, to concentrate attention on what is essential to the invention.
  • this fastener 5 On the side of the backing 1 which is opposite to the two adhesive layers, and which is also referred to in this specification as the bottom face, there is appropriately a separable fastening 5 whose purpose is to secure the new paper roll—which does not appear until FIG. 2 —against premature unwinding in the acceleration phase.

  • the splittable paper acquires the property of splittability by virtue of the fact that it is composed of two layers whose chosen cohesion is higher than the adhesion of the separable adhesive layer located between them or by virtue of the fact that the paper is more highly compacted in its surface regions and is therefore stronger than in its middle regions, or by virtue of other means.
  • the lower adhesive layer 5 . 3 of this separable fastener which is labeled 3 . 3 , has a liner tape.
  • This liner tape may also finish flush, but is preferably designed to protrude on at least one side, as shown here. It is also possible—as shown in FIGS. 8 to 14 —to omit the liner tape 3 . 3 entirely, if the liner tape 3 . 2 has release properties not only on its bottom face but also on its top face, as a result, for example, of waxing or siliconization. In that case the top face takes over the function of 3 . 3 as well.
  • FIG. 2 shows the same adhesive tape K as FIG. 1 , but here the lower liner 3 . 3 has already been removed and the adhesive tape K has been adhered by means of the adhesive layer 5 . 3 to the paper ply P 2 or winding second from the top of the new paper roll.

  • FIG. 6 shows the moment at which the new paper roll, prepared in accordance with FIG. 5 and brought to rotational speed n to an extent such that the web speed of its outermost winding P 1 , i.e., n ⁇ D, coincides substantially with the web speed of the old paper web, is led up to the end E of the old paper web and pressed against it, after which the two paper webs bond.
  • FIG. 7 shows the tearing of the fastener 5 of the new paper roll, which occurs about half a millisecond to one millisecond later, accompanied by detachment of the topmost ply P 1 of the new paper roll from its ply P 2 second from the top. Thereafter, it is also possible to remove its subsequent wound plies.
  • FIGS. 8 to 14 refer to the second, especially preferred exemplary embodiment, and show it in a completely analogous sequence. As was already the case in the preceding FIGS. 2 to 7 , in FIGS. 9 to 14 as well the slight curvature of the paper windings (roll diameter approximately 2 meters) in comparison with the width of the adhesive tape (preferably 7 cm) is disregarded.
  • FIG. 8 shows an adhesive splicing tape K of the invention whose adhesive area 2 . 1 disposed on its top face extends over the entire width of the adhesive tape. Position “b” has therefore shifted rightward to such an extent that it comes to lie exactly below position “d”.

  • FIG. 14 starting from a web speed of approximately 120 km/h, shows the tearing of the fastener 5 , which takes place about half a millisecond to one millisecond later, between the two peripheries P 1 and P 2 of the new paper roll. After this opening of the fastener, the following wound plies can also be removed.
  • the invention teaches building of a larger compression between the two webs at the beginning of contact of the new, prepared web with the old web, in order to allow better toleration of the small, unavoidable synchronization deficits when carrying out a flying splice.
  • a concentration of compression at the beginning of the bonding sites in this way is achieved by placing two adhesive layers one above the other in at least a small region of overlap.
  • both adhesive layers are composed of different adhesives, with the first adhesive layer, which is intended for attachment to the start (A) of the new roll, being developed for a particularly high shear resistance, even if this is in competition with the achievable tack, while the second adhesive layer, which is intended for attachment to the end of the old, expiring material web, being developed for a higher tack.
  • An adhesive tape of the invention can be produced with particular ease if the first adhesive layer is applied over the full width of the adhesive tape while the second occupies only one region—the front region as viewed in the running direction of the material web direction [sic] to be joined; in that case the region of overlap of the two layers is large and is identical with the region of extent of the second layer.
  • the invention serves in particular to reduce further the rate of those tears which might be connected with a splice.
